Previous reports suggested the existence of direct somatic motor control over heart rate (fH) responses during diving in some marine mammals, as the result of a cognitive and/or learning process rather than being a reflexive response. This would be beneficial for O2 storage management, but would also allow ventilation-perfusion matching for selective gas exchange, where O2 and CO2 can be exchanged with minimal exchange of N2. Such a mechanism explains how air breathing marine vertebrates avoid…

Respiratory sinus arrhythmia and submersion bradycardia in bottlenose dolphins (<italic>Tursiops truncatus</italic>)
TLDR
It is found that dolphins exhibit a pronounced respiratory sinus arrhythmia during surface breathing, resulting in a rapid increase in fH after a breath followed by a gradual decrease over the following 15–20 s to a steady fH that is maintained until the following breath.
Respiratory sinus arrhythmia and submersion bradycardia in bottlenose dolphins (Tursiops truncatus)
TLDR
The results demonstrate that the fH patterns observed during submerged breath-holds are similar to those resulting from RSA during an extended IBI, highlighting the importance of RSA in influencing fH variability and emphasize the need to understand its relationship to submersion bradycardia.
Scaling of heart rate with breathing frequency and body mass in cetaceans
TLDR
Data show that surface fHs of cetaceans are complex and the fH patterns observed are controlled by several factors, and suggest the importance of considering RSA when interpreting fH measurements and particularly how fR may drive fH changes that are important for efficient gas exchange.
An integrated comparative physiology and molecular approach pinpoints mediators of breath-hold capacity in dolphins
TLDR
It is suggested that ALOX5 may play a role in the dolphin’s physiological response to diving, particularly in a pro-inflammatory response to ischemia and in promoting vasoconstriction.
A Baseline Model For Estimating the Risk of Gas Embolism in Sea Turtles During Routine Dives
TLDR
A mathematical model to estimate partial pressures of N2, O2 (PO2), and CO2 (PCO2) in the major body-compartments of diving loggerheads, leatherbacks, and green turtles suggests that cardiac output likely plays a significant role in the modulation of GE, especially in the deeper diving leatherback turtles.
How Do Marine Mammals Manage and Usually Avoid Gas Emboli Formation and Gas Embolic Pathology? Critical Clues From Studies of Wild Dolphins
Decompression theory has been mainly based on studies on terrestrial mammals, and may not translate well to marine mammals. However, evidence that marine mammals experience gas bubbles during diving…
An external telemetry system for recording resting heart rate variability and heart rate in free-ranging large wild mammals
TLDR
A robust, externally mounted heart rate monitor for use in wild mammals, deployed here on wild breeding adult female grey seals, that delivers millisecond precise measures of inter beat intervals (IBIs), allowing computation of resting HRV parameters is described.
Microscopic anatomical, immunohistochemical, and morphometric characterization of the terminal airways of the lung in cetaceans
TLDR
The results contribute to the current understanding of the anatomy of the terminal airways of the cetacean lung and the role of the smooth muscle in the alveolar collapse reflex, crucial for prolonged breath‐holding diving.
Too big to study? The biologging approach to understanding the behavioural energetics of ocean giants.
TLDR
This Review outlines how the energy expenditure and intake of free-living ocean giants could be studied using 'biologging' technology and outlines how information on energy intake and foraging behaviour can be gained from tag data.
Wearable Near-Infrared Spectroscopy as a Physiological Monitoring Tool for Seals under Anaesthesia
TLDR
NIRS data from 10 trials of prolonged anaesthesia induced through ketamine and midazolam in five grey seals involved in other procedures support the use of NIRS as real-time physiological monitoring tool during pinniped chemical immobilisation.

Ventilation and gas exchange before and after voluntary static surface breath-holds in clinically healthy bottlenose dolphins, Tursiops truncatus
TLDR
Evaluation of how lung function and end-expiratory gas concentration change during recovery following a static breath-hold in dolphins suggests that the dolphins attempt to minimize recoveryFollowing a dive by altering VT and fR to rapidly replenish the O2 stores.
Re-evaluating the significance of the dive response during voluntary surface apneas in the bottlenose dolphin, Tursiops truncatus
TLDR
Data highlight the necessity to define how the resting fH is estimated at the surface, and separating it from the RSA associated with each breath to evaluate the significance of cardiorespiratory matching during diving.
Cognitive control of heart rate in diving harbor porpoises
Resting Metabolic Rate and Lung Function in Wild Offshore Common Bottlenose Dolphins, Tursiops truncatus, Near Bermuda
TLDR
The lack of respiratory adaptations for deep diving further support the recently developed hypothesis that gas management in cetaceans is not entirely passive but governed by alteration in the ventilation-perfusion matching, which allows for selective gas exchange to protect against diving related problems such as decompression sickness.
Pulmonary ventilation–perfusion mismatch: a novel hypothesis for how diving vertebrates may avoid the bends
TLDR
This hypothesis provides avenues for new areas of research, offers an explanation for how sonar exposure may alter physiology causing GE and provides a new mechanism for how air-breathing marine vertebrates usually avoid the diving-related problems observed in human divers.
Using Respiratory Sinus Arrhythmia to Estimate Inspired Tidal Volume in the Bottlenose Dolphin (Tursiops truncatus)
TLDR
This study investigated whether the respiratory sinus arrhythmia (RSA) could estimate tidal volume (VT) in resting bottlenose dolphins (Tursiops truncatus), allowing VT to be studied in free-ranging animals provided that heart rate can be measured.
Cardiorespiratory coupling in cetaceans; a physiological strategy to improve gas exchange?
TLDR
Results show that cetaceans have a strong Respiratory Sinus Arrythmia (RSA), during which both fH and SV vary within the interbreath interval, making average values dependent on the breathing frequency (fR).
PHYSIOLOGY WITHOUT RESTRAINT IN DIVING MAMMALS
TLDR
This discussion shows the limitation of present data and the type of data needed to resolve the question of how aquatic vertebrates manage O2 stores during dives of varying durations.
Drivers of the dive response in pinnipeds; apnea, submergence or temperature?
TLDR
The voluntary dive response in pinnipeds is driven primarily by apnea and intensified by increased facial immersion and decreased water temperature, and bradycardia is strengthened by both increasing the area of facial submersion and colder water.
Heart rate during breath-holding and diving in the unrestrained harbor seal (Phoco vitulina richardi).
TLDR
Monitoring of unrestrained harbor seals concluded that the generation of diving bradycardia is a facultative response, and respiratory variations in the heart rate occurred when breathing rate was low, although the onset of brady Cardia was much more rapid during diving than during breath-holding.
